1 This invention relates'to afoldable extension device frequently called a buckle, for temporarily enlarging the encircling size of a Wrist `band,*bracelet or the like, and has for '5 its objectl toprovide an. adjustment by Which V the encircling size ofvthe bracelet in Which it is .connected may'be changed. y 'A further .object of the invention is to provide a construction in which the bracelet may 'l m bexdetached from the extension device for removing a link or other manipulation and adjustably securedthereto. v 1

' A still further object of the invention is to provide a device which Will be thin, compact l and' comfortable towear, and Which may-be securelyheld' in folded position.A

A still further object of the invention is to provide va simple construction by Which these V desirable .results are accomplished, and one 20 Which may be easily fmanufacturedin multiple units and assembledwithout the use of With these and other Objects andadvantageous features in view, the invention con- '25 sists of a novel arrangement of parts more fully disclosed in the detailed description following, in conjunction vvith the accom- .panying dravvings, and moreV particularly set forth in the appended claims.

justment for the encircling size of the brace- .2

let With the other sections folding into the adjustable means and between the ends of `'this U-link so that a compact assemblage may be formed When in folded position With- :out unduly increasing the thickness of the device to the discomfortof the user; and the following is ka'detailed description of the present embodiment of this invention illus- .trating the preferredmeans by Which these advantageous results may be accomplished.

With reference to the drawings, 15 designates the frame links of they bracelet which are hingedly joined together'by a connector 16, the end link 17 being permanently attached to the device, and the end link 18 being joined to the connector member 19 which is a part of the connecting device, and which is adjustable With reference to the sections, as Will more fully hereinafter be described.

The extension device consists of a channel section 20 having a top Wall 21,,side Walls 422 With inturned edges or flanges 23. A'plate section 24 is provided With trunnions 25 eX- tending into the openings 26 in the sidewalls 22 to hinge'fthe same thereto, and about the trunnions 25 there is also pivotally mounted a channel member 27 having a top vWall 28, "side Walls 29, and ylateral extensions 30 provided With ears 31 having openings 32 therein 19 thereto in assembled relation.A Referring channel member, a plurality of sections foldsaid sectionretaining said arms With their detents in said opening butfbeing resilient to prevent said connector members bemg sWung from beneath said flanges and with said channel member about the p'ivot of the channel member, Whereby disconnection or adjustment of the connector member may be effected.

' 8. lIn an extension device, a channel section,

means for adjustably connecting a bracelet end thereto comprising` a channel member secured and housed Within said section and a connector member adjustablylsecured to said able one on the other hinged to said channel section and of a width to be housed within said 'channel member, means for releasably i securing said sections in housed relation, and

means for securing the other end of the bracelet to one of said sections.l

9. In an extension device, a channel section, means for adjustably connecting a V ,bracelet end thereto comprising a channel member secured and housed within said section and a connector member adjustably secured to said channel member, a plurality of sections foldable one on the other hinged to said channel section yand of a Width to be housed Within said channel member, means for releasably securing said sections in housed relation A comprising laterally extendingk Wings on one vof said. sections to engage the sidewalls of said channel section, and means for securing the other end of the bracelet to one of said sections.

10. In an extension device, a channelsection, means for adjustably connecting a bracelet end thereto comprising a channel member pivotally secured and housed Within said section anda connector member adjust- *ably secured to said channel member, a plu rality of plate sections'foldable one on the other hinged to said channel section and of a Width to be housed' within said channel member, means for releasably securin ksaid 'sections in housed relation, and means or securing the other end ofthe bracelet to one of said sections. V v e 11. In an extension device, ay channel section, means for adjustably connecting a bracelet end thereto comprising a channel member pivotally secured and housed within said section and a connector member adjustably secured to said channel member, a plurality of plate sections foldable one on the other hinged to said channel section and of a Width to be housed within said channel member, means for releasably securing said sections in housed relation comprising later- `ally extending Wings on one of said sections to engage the side vvalls of said channel section, and means for securing the other end of the bracelet to one of said sections.
